the seriousness is classified by the following indications.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties.
• The items to be followed are classified by the symbols:
This symbol denotes item that is PROHIBITED from doing.
• Carry out test run to confirm that no abnormality occurs after the servicing. Then, explain to user the operation, care and
maintenance as stated in instructions. Please remind the customer to keep the operating instructions for future reference.
1. Do not modify the machine, part, material during repairing service.
2. If wiring unit is supplied as repairing part, do not repair or connect the wire even only partial wire break. Exchange the whole wiring
unit.
3. Do not wrench the fasten terminal. Pull it out or insert it straightly.
4. Engage dealer or specialist for installation and servicing. If installation of servicing done by the user is defective, it will cause water
leakage, electrical shock or fire.
5. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electric shock or fire.
6. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water
leakage, fire or electrical shock.
7. Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not
properly done, the set will drop and cause injury.
8. For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and
single outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or
fire.
9. This equipment is strongly recommended to install with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD).
Otherwise, it may cause electrical shock and fire in case equipment breakdown or insulation breakdown.
10. Do not use joint cable for indoor / outdoor connection cable. Use the specified Indoor/Outdoor connection cable, refer to installation
instruction CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor / outdoor connection. Clamp the cable so
that no external force will be acted on the terminal. If connecting or fixing is not perfect, it will cause heat up or fire at the connection.
11. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will
cause heat-up or fire at the connection point of terminal, fire or electrical shock.
12. When install or relocate air conditioner, do not let any substance other than the specified refrigerant, eg. air etc. mix into refrigeration
cycle (piping). (Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.)
13. Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit at veranda of high rise building, child may
climb up to outdoor unit and cross over the handrail and causing accident.
14. This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and
telephone. Otherwise, it may cause electric shock in case equipment breakdown or insulation breakdown.
15. Keep away from small children, the thin film may cling to nose and mouth and prevent breathing.
16. Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with
other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.
17. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare
may break and cause refrigerant gas leakage.
3
18. For R410A models, when connecting the piping, do not use any existing (R22) pipes and flares nuts. Using such same may cause
abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. In case of using existing (R22)
pipes during installation of R410A models, must carry out pump down properly to collect back the refrigerant and oil before installation
new unit.
Thickness of copper pipes used with R410A must be more than 0.6mm. Never use copper pipes thinner than 0.6mm.
It is desirable that the amount of residual oil is less than 40 mg/10m.
19. During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing
refrigeration piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in
explosion, injury etc.).
20. During pump down operation, stop the compressor before remove the refrigeration piping. (Removal of compressor while compressor
is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion,
injury etc.)
21. After completion of the installation servicing, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the
refrigerant contacts with fire.
22. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fire.
23. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
24. Must not use other parts except original parts describe in catalog and manual.
1. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the
unit, it may cause fire.
2. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage
the furniture.
3. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare
may break and cause refrigerant gas leakage.
4. Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.
5. Select an installation location which is easy for maintenance.
6. Pb free solder has a higher melting point than standard solder; typically the melting point is 50°F - 70°F (30°C - 40°C) higher. Please
use a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
Pb free solder will tend to splash when heated too high (about 1100°F / 600°C).
7. Power supply connection to the conditioner. Connect the power supply cord of the air conditioner to the mains using one of the
following methods.
Power supply point shall be the place where there is ease for access for the power disconnection in case of emergency. In some
countries, permanent connection of this room air conditioner to the power supply is prohibited.
1. Power supply connection to the receptacle using a power plug. Use an approved 15/16A (3/4~1.5HP) or 16A (2.0HP) or 20A
(2.5HP) or 25A (3.0HP) power plug with earth pin for the connection to the socket.
2. Power supply connection to a circuit breaker for the permanent component. Use an approved 16A (3/4~2.0HP) or 20A (2.5HP)
or 25A (3.0HP) circuit breaker for the permanent connection. It must be a double pole switch with a minimum 3.0 mm contact
gap.
8. Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigeration parts. Take
care of the liquid refrigerant, it may cause frostbite.
9. Installation or servicing work: It may need two people to carry out the installation or servicing work.

NOTE
• Thoroughly study the following installation locations
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo fan, the fin of
the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dispersing of water drops, drain
pump malfunction, etc.
In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily
steam which should not flow into the suction of the air conditioner.
• Make enough distance from the cooking room to install the air conditioner in such place where it may not suck in oily
steam.
2. Avoid installing the air conditioner in such circumstances where cutting oil mist or iron powder exist especially in factories,
etc.
3. Avoid places where inflammable gas is generated, flows-in, contaminated, or leaked.
4. Avoid places where sulphurous acid gas or corrosive gas can be generated.
5. Avoid places near high frequency generators.

REFRIGERANT PIPING
Refrigerant is charged to the outdoor unit. For details, see the
manual for installation work of outdoor unit. (Additional
charging, etc.)
1. Brazing for piping.
a. Execute brazing before tightening the flare nut.
b. Brazing must be executed while blowing nitrogen gas.
(This prevents generation of oxidized scale in copper
pipe.)
2. When there is a lot of brazings for long piping, install a
strainer midway of the piping. (The strainer is locally
supplied.)
3. Use clean copper pipe with inner wall surface free from
mist and dust. Blow nitrogen gas or air to blow off dust in
the pipe before connection.
4. Form the piping according to its routing. Avoid bending
and bending back the same piping point more than three
times.
(This will result in hardening of the pipe).
5. After deforming the pipe, align centers of the union fitting
of the indoor unit and the piping, and tighten them firmly
with wrenches.
6. Connect pipe to the service valve or ball valve which is
located below the outdoor unit.
7. After completed the piping connection, be sure to check if
there is gas leakage in indoor and outdoor connection.
Vacuum drying
After completing the piping connection, execute vacuum drying for the connecting piping and the indoor unit.
The vacuum drying must be carried out by using the service ports of both the liquid and gas side valves.

INDOOR UNIT DRAIN PIPING
• During drain piping connection, be careful not to exert extra force on the drain port at the indoor unit.
• The outside diameter of the drain connection at the indoor unit is 32mm.
Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings.
• Be sure to perform heat insulation on the drain piping.
Heat insulation material: Polyethylene foam with thickness more than 8 mm (local supply).
• Drain piping must have down-slope (1/50 to 1/100); be sure not to provide up-and-down slope to prevent reversal flow.
• Be sure to check no air trap on drain hose and to ensure smooth water flow and no abnormal sound.
• The height of drain may be possible up to 750 mm.
Drain Test
• When drain set piping, install as shown in the figure below.
The air conditioner uses a drain up motor to drain water. Use the following procedure to test the drain up motor operation.
•
•
•
•
•
Connect the main drain pipe to exterior and leave it provisionally until the test comes to an end.

HEAT INSULATION
Be sure to perform heat insulation on the drain, liquid and gas piping. Imperfection in heat insulation work leads
to water leakage.
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over 120°C).
2. Precautions in high humidity circumstance.
This air conditioner has been tested according to the “JIS Standard Conditions with Mist” and have been confirmed that there
are no faults. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23°C),
water drops are liable to fall. In this case, add heat insulation material according to the following procedure:
• Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20 mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
• In addition to the normal heat insulation (thickness: more than 8 mm) for refrigerant piping (gas piping: thick piping) and drain
piping, add a further of 10 mm to 30 mm thickness material.
Wall seal
• When the outdoor unit is installed on a higher position than
the indoor unit, install the trap so as not to instill rain water
into the wall by transmitting in piping.
• Stuff the space among piping, the electric wire, and the drain
hose with “Putty” and seal the penetration wall hole.
Make sure that rain water do not instill into the wall.

12 Operation and Control
12.1. Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,
automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the
microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature
shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that
judging the condition according to internal setting temperature and intake air temperature.
12.1.1. Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes.
These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value
will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.
12.1.2. Cooling Operation
12.1.2.1. Thermostat control
